Finding the right part number shouldn't mean a wasted trip to the dealer. This Kubota BT 751 Parts Catalog runs 53 pages and 25 exploded-view diagrams, mapping every assembly on the backhoe: main frame, swing cylinder, bucket link, stabilizer arms (both LH and RH), and the dual control levers. Hydraulic coverage goes deep, with four hose routing diagrams (inlet/outlet, boom/dipperstick, bucket, and stabilizer) alongside full control valve component parts marked with interchangeability symbols. Every diagram sits next to a numbered parts list, so any component cross-references in seconds. The control valve relief is set at 2,525 PSI; the boom pin measures 1.18 × 8.62 inches. Stop reading part numbers off a worn casting by flashlight. Sections are bookmarked by assembly, keyword search works anywhere, and the whole file pulls up on your phone at the machine.

Kubota BT751 Common Problems This Manual Covers
Kubota BT 751 boom and dipperstick hydraulic hose part numbers unclear after disassembly or cylinder work p. 41
Open the Hydraulic Hose (Boom Dipperstick) exploded view on page 41. Match each hose by its position in the routing diagram, end fitting type, and cylinder connection point. The parts list here gives individual part numbers; cross-reference by position number rather than length alone, since several hoses on this backhoe share similar dimensions and get mixed up during reassembly.
Manual Section: Hydraulic Hose (Boom Dipperstick)Bucket link pins and bushings worn, need exact replacement part numbers for pivot hardware p. 19
Turn to the Bucket Link exploded view on page 19, where each pin and bushing is numbered by pivot location. The bucket link pin measures 0.98 x 6.68 in. (page 20); bushings are listed separately with a per-assembly quantity in the parts list. Check that quantity before ordering so you get the full set of replacements.
Manual Section: Bucket LinkSwing cylinder bushing part number unclear in exploded view, hard to distinguish from seals and washers p. 7
Locate the swing cylinder bushing on the page 7 exploded view, labeled by position number at the cylinder mounting point. The parts list on page 8 carries it at 0.044 lb.; use that weight to confirm you have the right line item, not a similar-looking seal or washer in the same assembly.
Manual Section: Swing CylinderStabilizer cylinder LH and RH part numbers mixed up when ordering replacement seals or head components p. 27
Check page 27 for left-hand stabilizer cylinder components and page 29 for the right-hand assembly; these are separate sections, and the part numbers do not interchange. The LH cylinder head measures 2.50 x 1.38 in. (page 28). Confirm which side you are working on before pulling part numbers, since ordering the wrong side is the most common mistake on this assembly.
Manual Section: Stabilizer Cylinder Lh (Component Parts)Boom cylinder internal component parts unclear, need part numbers for head or seals after disassembly p. 13
Flip to the Boom Cylinder (Component Parts) diagram on page 13. The exploded view breaks out every internal piece individually: head, piston, seals, and rod assembly. The cylinder head measures 2.75 x 1.38 in. (page 14); verify that dimension against your cylinder before recording part numbers, since the dipperstick and stabilizer sections share a similar layout and are easy to confuse.
Manual Section: Boom Cylinder (Component Parts)Control valve internal component part numbers needed to replace relief valve or seals after disassembly p. 35
Identify the internal components on the Control Valve (Component Parts) diagram on page 35, each numbered individually in the exploded view. The relief valve is rated at 2525 PSI (page 36); match that spec when ordering a replacement to avoid a wrong-pressure unit. The parts list breaks out seal kit components and quantities for each sub-assembly in the valve body.
